1. General Description of the Pro gram
The Sub-project 4 investigates innovative, intelligent and hig h-performance multimedia mobile communication and network solutions for ITS. There are four main tasks in Sub-project 4, including development of and/or investigation on wireless/mobile access networks, heterogeneous network integration, intelligent in -car human-machine interfacing by reliable speech recognition, and advanced ITS information-communication platform for automotive telematics. In the first year, a convergent automotive telematics is architectured and designed for further integration of other sub-projects. A novel hybrid mobile access network, which combines WLAN-based MANET and commercially available 2.5G/3G cellular network s, is proposed and investigated. Considering heterogeneous network convergence, a mathematical model is developed to evaluate the possibility of cognitive radio (CR) network to resolve the opportunistic radio resource management and medium -access control issues for ITS. A speech recognition system is established on an embedded platform for human-machine interface to access re mote traffic information and to easily control various in-car equipments.
2. Breakthroughs and Major Achievements
In the second year of this program, major achievements and breakthroughs are summarized as follows:
Heterogeneous Network Simulation
A network simulator capable of simulating both vehicular network and traffic has been designed and implemented. When compared with other network simulators, our network simulator has several unique advantages:
(1). It can directly run real-world application programs during simulation. This means that developing application programs over our simulator can minimize the time and effort required to port such developed programs from the simulation environment to the real world.
(2). It tightly integrates vehicle traffic simulation and vehicle network simulation together and provides real -time feedback loop between them. This enables novel ITS research in which a vehicle needs to change its moving speed or direction after receiving a message from another vehicle.
(3). Since its release in Nov. 2002, as of Dec. 6, 2007, the number of registered users of this simulator has exceeded 10,251. These users come from 121
countries in the world and these numbers are still increasing.
Smart and Cognitive Communications and Netw orks
(1). A method to design the optimal relay location is developed, aiming to maximize the system throughput in the two-hop wireless ITS systems. This method also suggests a relay selection rule to determine whether the data are delivered by two-hop transmissions. Based on the suggested relay selection rule, the throughput can be improved when the relays are deployed at the proper locations. In addition, we find the optimal relay location to maximize the system throughput.
(2). A scalable ring-based wireless multihop network for wide -area coverage is proposed. In multihop networks, i nner users consume more power to relay traffic than others, thereby leading to the power-unfairness issue in the multihop network. We suggest designing the ring widths to achie ve power fairness and extend the lifetime of multihop network. We also apply an optimization approach to determine the optimal widths of the rings in a multihop network, aiming to maximize the cell capacity and coverage subject to the constraint of power fairness.
Intelligent in-car human-machine interface
(1). The eASR system and the TTS system in a hand-held mobile device
We implement an embedded automatic speech recognition system (eASR) and a Text-to-Speech (TTS) system on a hand -held device. The eASR adopts the initial-final HMM-based approach. It uses the fixed -point partition Laplacian observation probability to model the RASTA -based MFCCs. The precision of the fixed point data used in the system was 32 bits (16*16 operations). The ASR system can be run in two modes: isolated -word recognition and keyword spotting. For an application of 1000 isolated words, the recognition rate is 93.9% in clean-speech environment. The recognition rate degrades slightly to 91.3% for a noisy car environment with 6 dB in SNR. The system response time is about 1.1 times of the recording time operating in 200MHz Arm9-based platform. The TTS system is a revised version of the one originally developed on SunPlus un’SP 6608 DSP by Prof. Shaw -Hwa Hwang of the Department of Electrical Engineering, National Taipei University of Technology. The system uses segment-based 411 base-syllables as synthesis units and adopts a recurrent neural network to generate prosody information. It can synthesize natural Mandarin speech for any input Chinese texts. The specifications of the eASR
and TTS systems are listed in the following table.

Design and Prototyping of Automotive Telematics
(1).An IPv6-based automotive telematics is developed to investigate IPv6 networking systems for ITS. Several advanced networking protocols, inc luding IPv6, Mobile IPv6, and NEMO protocols, are planned to be integrated in the platform. The prototype is made for field trials and performance evaluation purposes. The telematics hardware/software platform is based on an embedded hardware platform with an ARM-based microprocessor, graphic/vocal human-machine interfaces (HMI), and heterogeneous network devices (IEEE 802.11b WiFi with MANET capability, GPRS, GPS) are suggested. Telematics service prototypes, such as traffic information on demand and inter -vehicular driving assistance, are developed for proof -of-concept experiments.
(2). A 2-D geometric and adaptive relay node deployment method is proposed to minimize relay nodes for bridging all disconnected Road -Side Units (RSU), which are regarded as an enabling technology for vehicle -to-infrastructure (V2I) communications. This method only has polynomial -time complexity. In the method, the local optimum location of the relay node is discovered on a plane, which gives a much larger degree of freedom to c ompare with the traditional 1-D search algorithm. Besides, the method can also adapt to radio environments because that a sophisticated propagation model including large -scale path loss, shadowing, and multipath fading effects is used to estimate link conn ectivity. Simulation result validates its robustness and efficiency compared with related works.

2) Summary of the Research Outcomes Task 1: Wireless/mobile access networks
1) The simulator integrates both vehicle traffic and vehicle network simulations and provides a feedback loop between them. Therefore, it enables advanced novel ITS research where the communication result may affect the movements of vehicles. 2) The simulator allows a user to easily construct a simulated road network and
simulate vehicles moving on the simulated road. The moving behavior of a simulated vehicle on the road is controlled by a car agent program, which implements realistic car-following and lane-changing behavior. The message communication among cars is also implemented in the car agent program. Novel
advanced ITS communication network system/protocol designs can be tested and evaluated under this network simulator.
3) The simulator has been introduced to and published at 1st IEEE WiVec 2007 (International Symposium on Wireless Vehicular Communications), September 30 – October 1, 2007, Baltimore, MD, USA conference .
Task 2: Heterogeneous network integration and radio resource management
1) Optimal relay location design in two -hop wireless ITS systems: This project investigates the optimal relay location for wide-area coverage, aiming to maximize system capacity. We consider two relay selection rules to determine whether a two-hop transmission is necessary, including the signal strength-oriented and throughput-oriented rules. It is shown that the signal strength -oriented two-hop transmission may yield lower throughput than the one-hop transmission. The throughput-oriented rule can improve the throughput if the relays are deployed at the proper locations. For the throughput-oriented rule, we also determine the optimal relay location to maximize the system capacity.
2) Power Fairness in a ring-based wireless multihop network: This project develops a scalable ring-based wireless multihop network with power fairness. We investigate the overall tradeoffs of the ring-based multihop network in terms of power fairness, capacity, and coverage. In multihop network, inner users consume more power to relay traffic than others. By properly designing the ring widths, power fairness can be achieved and the lifetime of multihop network can be extended. An optimization approach is also applied to determine the optimal ring widths, aiming to maximize the cell capacity and coverage subject to the constraint of power fairness.
Task 3: Intelligent in-car human-machine interface
1) A real-time corpus-based Mandarin TTS system was developed. The study focuses on how to design a corpus and how to select best segments from the corpu s. The system has four modules. Among them, three modules are inherited from our old system. They are the text analyzer (TA), the prosodic information generator (PIG), and the waveform synthesizer (WS). The other module, search -and-selection module (SS), is specially designed for the corpus -based approach. Its main function is to find all usable waveform segments in the corpus, and select the best combination to be directly concatenated for generating output speech.
2) Robust Speech Recognition: Robustness of automatic speech recognition (ASR) to various noisy environment s is the most important issue for mass deployment of ASR-based applications. To take the advantage of noisy environment knowledge and, at the same time, all eviate the problem of unseen noisy en vironments, a reference model weighting (RMW) approach is proposed for fast online HMM adaptation. The basic idea is to first collects a set of HMMs from seen noisy environments in the training phase to represent the space of noisy environments, and then optimally (in the sense of maximum likelihood) synthesize a suitable HMM online for the unknown test noisy environment by interpolating the set of the pre-collected HMMs in the test phase.
Task 4: Convergent ITS information -communication platform for autom otive telematics
1) A convergent information -communication automotive telematics platform has been developed with an ARM -based embedded systems. This platform integrates multiple radio communication technologies, including IEEE 802.11b WiFi, GPRS, and GPS, etc., for connecting heterogeneous wireless access networks.
2) The next-generation Internet protocol, IPv6 protocol, and several advanced mobility protocols, including mobile ad hoc routing protocol and mobile IPv6 protocol, have been developed and integrated in the telematics platform. These protocols fulfills future needs of inter -vehicular communications and mobile Internet access for ITS. For performance evaluation and demonstration purpose, an IPv6-based network platform for the auto -telematics is proposed.
3) We propose a relay node deployment method, which aims to minimize the total number of relay nodes for connecting RSUs effectively. In the method, the local optimum location of the relay node is discovered on a 2 -dimensional plane. This method is better than related works (that are based on 1 -D search algorithm) by nature since these relay nodes are allocated on a horizontal plane which gives a large degree of freedom. By considering radio propagation effect, a sophisticated propagation model including sha dowing and multipath fading is employed in estimating link connectivity, which can reflect radio channel effects more properly to compare with the traditional model, the Unit Disk Graph model utilized by most of existing works.
4. Program Management
Through the establishment of an innovative, intelligent and high -performance multimedia mobile communication and network solutions for ITS , all the tasks are highly correlated as shown in Fig. 1. The integration of these tasks will be realized on either the advanced simulation platform (managed by task 1) or the proof -of-concept telematics platform (managed by task 4). The proposed simulation platform integrats vehicle traffic simulation and vehicle network simulation, which enables advanced novel ITS research where the communication result may affect the movements of vehicles. Selected schemes for heterogeneous network integration (designed by task 2) would be developed on the simulation platform for further performance investigation. Oh the other hand, the te lematics has communication linkages using 2.5G/3G cellular, WLAN, and MANET for wide -area, hotspot, and inter-vehicle communications, respectively. For advanced human -machine interfacing for ITS applications, the intelligent in-car speech recognition techn ologies (designed in task 3) will be developed and integrated in the platform. Selected VPS services will also be developed to verify the capability of proposed telematics and wireless access technologies.

The research teams in this project worked very closely in the past years. In the second year, the research teams had their regular monthly meetings for discussing techical details, technical issues of achieveme nt integration, and administration affairs. We have identified the system architecture and design goals of the overall system and key components. The development status was, therefore, well under control. The frequency of meetings will be adjusted based on the program requirement, especially when the system integration task starts.
5. A Summary of the Post -Program Plan
In the second year, the prototypes of system modules for integrating of in -car speech recognition on the convergent automotive telematic s are developed. The functions of these modules are validated by field tests. Besides, the advanced simulation platform, which integrates data communication simulation and transportation traffic simulation, are developed. After that, the sub -project 4 will increasingly be devoted to not only the academic research on anticipated topics but also the large-scale system simulation, system integration and field-testing of these technologies. The system integration will be focused in the next year with specific t opics as follows:
(1) Enriching the voice -based telematics services for further performance investigation. Performance improvement and field-testing of the in-car speech recognition and its applications will be investigated. Inter -subproject integration is also planned in following years.
(2) Developing the software modules of proposed h eterogeneous network integration mechanism, i.e., vertical handover algorithm, on the NCTUns simulation platform. Based on the NCTUns platform, the performance of these mechanisms c ould be further evaluated in provisioned cases that represent the scenarios in real world. 6. International Cooperation Activities

APPENDIX IV: SLIDES ON SCIENCE ANDTECHNOLOGY BREAKTHROUGHS 1. Heterogeneous Network Simulation
The NCTUns network simulator tightly integrates vehicle traffic and vehicle network simulations and provides a feedback loop b etween them. It facilitates advanced and novel ITS research where a vehicle needs to change its moving behavior after receiving a message from another vehicle.
2. Smart and Cognitive Communications and Networks – Advanced communication and network techn ologies for ITS
Optimal relay location design in two -hop wireless ITS systems: We compare two relay selection rules. According to t hroughput-oriented rule, relay is used if it can achieve higher effective throughput. By signal strength-oriented rule, relay is used when it can provide stronger signal strength. The throughput-oriented rule can improve the throughput if the relays are deployed at the proper locations. We also determine the optimal relay location to maximize the system capacity.
1
Design of Optimal Relay Location in
Two-Hop Wireless ITS Systems
•
Objectives-– Find the optimal relay location.
– Suggest relay selection rule to maximize user throughput. – Achieved throughput v.s.
relay location Throughput-oriented : Higher throughput. Optimal location: 1273 m
Signal strength-oriented: Improper location, lower throughput due to two-phase transmission.
Power Fairness in a ring-based wireless multihop network: We suggest designing the ring widths to reduce the power consumption of inner users and then achieve the power fairness. It is shown that the goal of capacity enhancement with power fairness guarantee can be filled at the cost of coverage performance. In this example, when the cell coverage is reduced by 8%, the power fairness can be achieved and the lifetime of network can be increased by 32%.

Power Fairness in a Ring-based
Wireless Multihop Network
•
Objectives-– Develop a scalable and power-fair multihop network architecture for ITS wireless systems.
– Optimization approach to maximize cell capacity subject to the constraint power fairness.
Cell coverage is reduced by 8% to achieve power fairness, the network lifetime can be increased by 32%.
By properly designing the ring widths, power fairness index keeps at 0.9.
3.Real-time isolated-word recognition system in a hand -hold mobile device
The embedded ASR system and TTS system was realized on a Wi ndows-CE based PDA. The user can give the lexicon he wanted by editing a BIG -5 file. When the user talked to PDA, the waveform was recognized and the recognize result was synthesized as 8kHz pcm. A simple API was d esigned such that the others applications can easily using the isolated Mandarin word recognition system implemented.
4. Embedded Design for Info -Com Platform of Intelligent Vehicle
A convergent information -communication automotive telematics platform has been developed with an ARM -based embedded systems. The next -generation Internet protocol, IPv6 protocol, and several advanced mobility protocols, have been developed and integrated in the telematics platform. These protocols fulfills future needs of inter-vehicular communications and mobile Internet access for ITS.
